Will the GOP Support Trump if he wins?

Donald Trump has amazed the media this year. Starting very low in the polls, he has now won 3 out of 4 state contests — and is poised to win a number of other states tonight.

In past years, that might signal the beginning of the end of the process, as the Republican party would close ranks around a victor. But will that happen this year?

A number of leading Republicans have signaled they may not be ready to support a Trump run for President. Leading donors like the Koch brothers have so far stayed on the sidelines. Mainstream candidates may be uncomfortable with Donald's forthright language. There has even been talk of a Republican "third party" mainstream candidate if Trump wins the nomination.

Always in the past, the party has rallied — sometimes reluctantly — around the final candidate. Will 2016 be the exception if Trump wins? Look for telltale signs as returns roll in — and as people react — to what could be a strong night for Donald Trump on Tuesday.
